Title:
METHOD OF MISCIBLE INJECTION TESTING OF OIL WELLS AND SYSTEM THEREOF
Document Type and Number:
WIPO Patent Application WO/2009/134835
Kind Code:
A3
Abstract:
A method of determining reservoir permeability and geometry of a subterranean formation having a reservoir fluid including oil that has not been previously water-flooded includes isolating the subterranean formation to be tested; providing an injection fluid at a substantially constant rate from a wellhead to the formation being tested, wherein the injection fluid is miscible with the oil at the tested formation; sealing, at the top, the tested formation from further fluid injection; measuring pressure data in the tested formation including pressure injection data and pressure falloff data; and determining the reservoir permeability and geometry of the tested formation based on an analysis of the measured pressure injection data and the measured pressure falloff data using a well pressure model.
